sCre levels in patients undergoing RARP or ORP at the six allocated time points: Prior to surgery, immediately after surgery (POD0), POD1, 3 months after surgery, 1 year after surgery and 2 years after surgery. The number of patients with postoperative AKI on POD0 and POD1, based on the KDIGO criteria, are presented. None of 70 (0%) patients with ORP and 25 of the 187 (13.4%) patients with RARP met the KDIGO's AKI criteria on POD0 (Pearson's χ2 test; P=0.001). Additionally, 2 of the 70 (2.9%) patients with ORP and 3 of the 187 (1.6%) patients with RARP met the same criteria (P=0.517) on POD1. For reference, changes in eGFR are also presented in the upper right corner. data are presented as the mean ± standard deviation. sCre, serum creatinine; RARP, robot-assisted radical prostatectomy; ORP, open radical prostatectomy; POD, postoperative day; AKI, acute kidney injury; KDIGO, Kidney Disease: Improving Global Outcomes; eGFR, estimated glomerular filtration rate.
